OPERATOR’S MANUAL
CMA-9000 FLIGHT MANAGEMENT SYSTEM
INDEPENDENT OPERATION
In the independent mode of operation, all entries made on either FMS are not reflected on the other FMS.
However, the active or inactive flight plan can still be copied from one FMS to the other via the RTE XFILL
prompt (LSK 4L) on the RTE 1/1 page. If the navigation database or the operational program is not the same on
all FMSs when a flight plan transfer is attempted, the alert message “UNABLE FMS-FMS SYNC” is displayed on
the scratchpad line. When the flight plan transfer is completed, the copied flight plan appears as a modification
on the other FMS. The modified route becomes active by pressing [EXEC].
During independent operation and if the navigation mode is GPS, the alert message GPS-GPS POS
DISAGREE is displayed in the scratchpad if the FMS position is significantly different than that of the other FMS.
NOTE: Due to slight variations in the position computation made by each FMS, leg sequencing may not occur
at exactly the same time on all FMSs while in independent operation.
RADIO TUNING OPERATION – DUAL FMS or FMS and RADIO HEAD
The radio tuning feature may not use FMS cross talk to establish synchronization. Depending of the installation,
it may use burst tuning and the radios’ feedback to establish synchronization. Its operation will not be affected
by the selection of synchronized or independent mode of operation.
In a dual FMS architecture, when the standby frequency is entered, it is cross talked to the cross-side FMS
(both FMS always display the same standby frequency of the same radio).
EMBEDDED CALCULATOR/CONVERSION TOOL (if configured)
If any mathematical calculations are required, use the CALC/CONV 1/2 page.
Conversions from one unit to another (e.g.: Meters to Feet) can be performed using the CALC/CONV 2/2 page.
Refer to Appendix A for specific details.
